Newton's cradle, named after Sir Isaac Newton, is a device that demonstrates conservation of momentum and energy via a series of swinging spheres. When one on the end is lifted and released, the resulting force travels through the line and pushes the last one upward. The device is also known as Newton's balls or "Executive Ball Clicker".

Famous quotes containing the words newton and/or cradle:
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
“Silent waters rocking on the morning of our birth,
like an empty cradle waiting to be filled.
And from the heart of God the Spirit moved upon the earth,
like a mother breathing life into her child.”
—Gordon Light (20th century)
